a function gets called when the function name is followed by a a) semicolon (;) b) period(.) c) ! d) none of the above
printf(), scanf() these are a) library functions b) userdefined functions c) system functions d) they are not functions
why use functions a) writing functions avoids rewriting the same code over and over b) using functions it becomes easier to write programs and keep track of what they are doing c) a & b d) none of the above
why use "return" statement a) on executing the return statement it immediately transfers the control back to the calling program b) it returns the value present in the parentheses return, to the calling program c) a & b d) none of the above
any restrictions have on the number of 'return' statements that may be present in a function. a) no restriction b) only 2 return statements c) only 1 return statements d) none of the above
what are the advanced features of functions a) function declaration and prototypes b) calling functions by value or by reference c) recursion d) all the above
any "C" function by default returns an a) int value b) float value c) char value d) a & b
in case any function return float value we must declare a) the function must be declared as 'float' in main() as well b) the function automatically returned float values c) function before declared 'float' keyword d) all the above
we called a function and passed something do it we have always passed the "values" of variables to the called function. such functions calles are called a) calls by reference b) calls by value c) calls by zero d) none of the above
int i=3; this declaration tells the C compiler to a) reserve space in memory to hold the integer value b) associate the name i with this memory location c) store the value 3 at this location d) all the above
"%u" unsigned integer print the a) address of variable b) value of variable c) name of a variable d) none of the above
why arguments can generally be passed to functions a) sending the values of the arguments b) sending the addresses of the arguments c) a & b d) none of the above
the process of defining something in terms of itself is called (or) in C it is possible for the functions to call themselves. A function called a) nested function b) void function c) recursive function d) indifinite function
main use of recursive function a) processing speed high b) reduce program length/reduce repeated statements c) if you do not, use iterative methods like, for, while or do-while d) all the above
